JOSEPH C. MOSLEY, OF ST.. LOUIS, MISSOURI.

nLEcTmcnLty-cesnernn LocK.

To all 'whom- "it in .ag/ concern lie Lt known that I. JOSEPH C. Mosher. a

citizen of the vUnited States. residing in thc city of St. Louis and State of Missouri. have invented nen and useful Improvement-s in Electrically-Opcratcd Locks, .of which the following is a pecification.

rl`his invention rela-tes to improvements in electrically7 operated locks and has particular application toa coin controlled lock ln carrying out the present invention, it is my purpose to provide a lock of the class .cle` scribed which will he key controlled and 4constructed in such manner that the key cannot he removed from the lock until after a eoi'n g has been deposited therein and the lockingi `bolt actuated to locking position. ,f It is also my purpose to provide a look of i the type settorth which will be constructed i in Vsuch inanz'icr that should the locking bolt I fail to work for any maison. the Acoin de-l posited mayY be recovered hiv-thc user.

Furthermore, I aim to provide an elec-l trically operated coin controlled lock ivheref l fin the coin Will heautonnitically .thrown out "hf active position as the holt moves to lock.-

ing position and wherein the holt. after assuming locking position, will be relieved ot the intlueneeV of the .electro responsive device and placed under the control Aoi" the key of the llock so that the -bolt may be retracted by :the tev.

A further object .of the invention is the provision of a lock of this character wherein the key will be locked against, removal as thel latter is manipulated' to retract the bolt, thereb;7 preventing removal of the key from the lock when the latter is inactive.

lith the above and other objects in View, the invention consists in the construction, combination and arrangement of parte hereinafter set. forth. in and falling 'Within the scope of the claims.

In the accompanying drawings; Figure 1 is a. View in elevation of-a. locker equipped with a coin controlled electrically operated lock constructed in accordance with the present invention. Fig. 2 is a vertical sectional view through the casing `of the lock, the mechanism of the look being shown in -elevation. Fig. 3 is an enlarged fragmentary sectional view on the line 3 3 of Fig. 2. Fig. fl is a fraffmentarv sectional view on the line 4,4 of F 2, Fig. 5 is a sectional view on the line of Figi 2; Figr is a longi- Speccaton of Letters Patent.

l tudinal sectional .View through the lock casi ing showing a inodited form of mechanism. lfjg. 7 is a fragmentary sectional vView through the coin chute. i Referring now to the accompanying driewings in detail, the numeral l designates 'the casingof a lock. .vhicli'casii'ig may be construeted of aufY suitable .or desired material and of any desired outline. Slidably mounted within guides within the casing and adapted to be projected outwardly of one end wall of the easing is a. locking bolt-2 having `formed on its under surface a'dependng lug 3 and equipped zit-its inner end with an upstanding arm 4 .carrying Van armature 5 disposed within the influence of an electromagnet 6. Leading into the top of the casf ing adjacent to the end thereof opposite that through which the .holt is adapted to be pro )ected is a coin chute 7 arranged at an vangle thereof equipped iuteriorly with contacts 8, S suitably spaced apart and connected in series in an electric circuit with the magnet 6. By means of this-construction, it will be seen such coin will bridge the contactslS, 8 and so close the circuit of the magnet 6 whereby the latter will be energized and act upon the armature :3 with the effect to slide the locking bolt .2 to projected or lock-ing position.

Tinmediutely succeeding the moifemcnt of the locking holt to locking position, the coin bridging the contacts S, 8 is reino-.ved and this is accomplished, inthe present instance. through the medium of a horizontal bar 9 secured to the upper end of the arm 4 and disposed in a plane parallel with that of the locking holt and having the free end thereol .cut out as at 10 and working through a slot -termed in .the front wall of the coin chute 7 immediately adjacent to the lower end thereof. `When the bolt is retracted, as illustrated in Fig. 2. the cut out portion l()l thc channel in the coin chute 7 and as the har 9 is moved with the locking holt, under the action of the magnet 6,'the wall of the cut away portion 10 carries the coin out of engagement with the contacts 8, 8. A verof the casing 1 and is disposed in afplnne to one side of the coin chute 7 and adapted Ato receive the coin as the latter is -moved off of the contacts 8, 8 under the action of the cui; away portion of the arm lh Thus; as

of the lia-r 9 forms in eiect a continuation of to the vertical and having the lower -e'nd K that when a. eoin is depositedin the chute 7 tical `chute ll leads out of the lower edge the locking bolt is moved to locking position, the eoin is removed from the contacts S, and peruntted to drop into the chute 1l whesclrv the circuit through the mag'- net 6 is broken and the latter deinergized so thatthe locking bolt is relieved oi' the influence ot the magnet. The lower end ot this chute ll may conuuunicate with a suit.- al'fle coin receptacle as is obvious. `Formed in the 'front wall of the lock casing l. at a point below the locking bolt and in proximity to the lugr B is a, key hole l2. while suitably connected to the locking bolt at a point in advance ot' the lug i3 and depending therefrom is a right angled arm 15% ha ving the horizontal limb thereof extended rearwardly and forked or bifurcated as at le. 1.5 designates the shank of a key, carrying adjacent to its inner end, a wing 16 adapted to be passed through the key hole 12 and swung into engagement with the lug 3, when the bolt is in locking position, whereby such bolt may be retracted. The outer end ot the shank 15 is equipped with a manipulating head 1T and formed adjacent to such head with a groove 18 and as the bolt is retracted the 'forked end 14- of the horizon-- tal limb of the right angled arm rides into engagement with the groove. 18 in the keiv shank and so eliminates the possibility of removing theybolt from the lock after the key has been retracted.

In order that a coin deposited within the coin chute 7 may be recovered in the event of the mechanism of the lock failing to work for some reason or the like the lower wall of the coin chute 7 adjacent to its lower end is provided with a gate or trap 19 capable of swinging downwardly to an open position to establish communication between the chute 7 and an outlet chute Q0. This gate 19 is connected through the medium of a link with a lever 21 fulcrumcd between its ends and having the free end thereof connected with a push rod 2&2, a 'coiled expansion spring 23 encircling the last-named rod and acting upon the same to hold the latter at its limit of outward movement and the gate in closed position. From this construction, it will be seen that when the push rod 92 is moved inwardly against the action of the springl 23, the lever 21 will be .swung about its fulcrum to open the gate 19 and so permit thc` coin on the contacts 8, 8 to gravitate along the chute 20.

In F ig. l ot the drawings, I have shown my improved lock as applied to a. locker and in this instance the lock casing is set into a compartment formed in the door of the locker, the outer wall of such compartment being formed with a slot 24 registering with the upper end of the coin chute 7 and with an opening 25 below the slot and establishing communication between the lower end of the outlet chute 20 and a cup 26, such cup nueces being secured to the outer surface of the door and surrounding the opening :25.

therein.

In Fig. G ot the drawings, I have shown a modified construction ot' locking mechanism a lever 2T in lieu ot' the arm 1t. This lever' is tnlcrlnned between its ends as at and has the upper end thereof pivotally connected as at Q9 with the respective end of the rod 9 and equipped with an armature 30 disposed within the influence of the pole ot the magnet n. The lower end of this lever depends below the locking bolt '2- and has pivotally connect-cd thereto one end of a retaining link 3l formed with a slot 3:2 parallel with its lower edge and having its rear end opening into a relatively short slot 33 arranged at right angles to the irst slot. T hese slots receive a pin 34 carried by the adjacent face of the locking bolt 2 and when the magnet 6 is energized the lever '27 swings about its fulerum and so slides the locking bolt to locking position. In the swinging movement of the lever, the lower end thereot` act-mites the link 3l and slides the latter relatively to the bolt 2 so that the short slot 33 receives the pin 31. Thus. thc locking bolt is held securely in locking position. The link is placed in face to t'uce contact with the lug 3 and when the key is inserted in the key hole to engage the lug and retract the bolt, the link is first contacted by the wing of the key and elevated to release the pin 84, the wing subsequently engaging the lug to retract the bolt.

From the foregoing description taken in connection with the accompanying drawings, the construction, mode of ope 'ation and manner of employing my invention will be readily apparent.

It will be seen that I have provided a lock wherein the bolt is coin controlled, electrically operated to locking position and key operated to unlocking position and wherein the coin may be recovered by the user in the event of the .locking mechanism failing to work.

While I have herein shown and described one preferred form of my invention by way of illustration, I desire to have it understood that I do not limit or confine n'iyself to the precise details of construction herein described and delineated, as modication and variation may be made within the scope of the claims Without departing from the spirit of the invention.
